Question
Two particles A and B start from rest and move for equal time on a straight line. The particle A has an acceleration a for the first half of the total time and 2a for the second half. The particle B has an acceleration 2a for the first half and a for the second half. Which particle has covered larger distance?
✓

Answer

Second particle

Area under (v, t) graph gives displacement. For graph (2) area is more.

A cube of iron $($density $= 8000\ kg m^{-3},$ specific heat capacity $= 470J \ kg^{-1} K^{-1})$ is heated to a high temperature and is placed on a large block of ice at $0^\circ C$. The cube melts the ice below it, displaces the water and sinks. In the final equilibrium position, its upper surface just goes inside the ice. Calculate the initial temperature of the cube. Neglect any loss of heat outside the ice and the cube. The density of ice $= 900\ kg m^{-3}$ and the latent heat of fusion of ice $= 3.36 \times 10^5J \ kg^{-1}$.
